Abstract

The conducting composites were prepared by blending polypyrrole (PPy) as a conducting polymer and nylon6,6 as a matrix. In chemical polymerization of PPy, the oxidizing agent was $FeCl_3$ and dopant was alkylbenzenesulfonic acid, such as camphorsulfonic acid (CSA) or dodecylbenzene sulfonic acid (DBSA). The electrical conductivity and mechanical properties were measured for the amount of dopant and PPy complex, and these morphology observed. When it was doped with DBSA having long alkyl chain and added the PPy complex of 25 wt %, the electrical conductivity was increased up to 0.64 S/cm.
